To aZZ whom it may concern:

Be it known that I, Gnonen H. \Vnnrms, a citizen of the United States of America, residing in the city of Greenfield, county of Franklin, and State of Massachusetts, have invented certain new and useful Improvements in Devices for Filling Pipe- Joints, of which the following is a specification.

This invention relates to improvements in devices for running or filling pipe joints, particularly for directing the flow of molten material, as lead into the annular space be tween the spigot and bell end of two adjoining pipes. This invention relates to the type of devices shownin the United States Patent granted to F. J. Hatch, No; 948,686, dated Feb. 8, 1910, in. which a rope or flexible packing belt is tightly clamped about the spigot end of a pipe section and close to the bell end of the adjacent pipe section; the clamping means being provided with a spout-like structure for directing the flow of the molten material to the joint inside of the rope, the rope serving the purpose of preventing the molten material from escaping from the annular chamber in the bell.

The present invention, broadly, comprises two rope clamping members which are pivoted together intermediate of their ends, one end engaging the rope and the other adapted to be grasped by the operator to open the clamp, whereby the rope can be readily inserted and drawn around the pipe thus binding it tightly to the pipe.

tightly. The clamps are automatically forced against the rope by means of a spring, The present device is one that can be readily formed by stamping or die work and is one that can be constructed at a low cost.

Referring to the drawings:v

Figure 1 is a perspective view showing the devicein use with the rope clamped between the plates thereof, and illustrating the pouring spout, the lower end'of which lies within the meeting ends of the rope at the upper side of the pipe;

Fig. 2 is a perspective view with the rope removed showing th manner of pivotally connecting the clamping plates together, also the spring, the opposite ends of which ends and located back of the connecting arms of the plates.

Referring to the drawings in detail: 1 designates the bell end 2 the spigot end of two pipe sections. 8 is the packing rope, preferably composed of asbestos or some suitable composition that is flexible and that will withstand high temperatures. This rope is passed around the pipe 2 and in contact with the collar 3. The free ends t and 5 of the rope pass upward between the clamping surfaces 6 and 7 of the plates 8 and 9. These plates are formed with inwardly extending arms 10 and 11 for the purpose of pivotally attaching the plates together by means of the pivot shown at 12. A stop 18 is secured to a part of arm 10 and serves as a limiting stop for the overhanging lip 14: which lip is preferably made integral with the part 10 which passes behind the arm 11 and upward and then over the top of the arm 11 and then downward as shown. This stop device limits the inward movement of the lower ends 6 and 7 inorder to permit the rope 3 to be inserted without having to move these ends through a long arc, as would be the case if the stop device did not hold them separated against the action of the operating spring. When the rope is in place, as shown in Fig. l the spring then exerts its force on the rope. In order to normally force the rope clamping plates 6 and 7 inward and toward each other, which are located at the lower ends of the arms 8 and 9, a stifi spring having a coil 15 intermediate of its length is attached to the arms 8 and 9 at their upper ends by means of the extensions 16 and 17 which are passed through openings in the upper ends of these arms, as shown. Formed integral with the plates and arm 8 is the inclined pouring spout or mouth portion 18 which is connected to the clamping surface 6 by means of the neck portion 19. Integral with the portion 18 is the downwardly extending triangular shaped end or side plate 20, the lower horizontal edge 21 of which rests upon the pipe 2, when in use, as shown in Fig. 1. It will be seen that the curved surface 18 which is located between the neck portion 19 and the triangular portion 20 is inclined to the horizontal plane so that the molten material when it is poured into the upper end of the inclined pouring spout or mouth portion 18 readily flows downward to the lower canfiow to completely fill this space without.

any of it escaping since the rope 3 is tightly clamped around the pipe 2 and' against the bell. The lower end of the portion 18 is slightly cut away, as indicated at 23, in order that there may be no clogging of the molten.

material at this point and to permit the spout to closely fit the pipe. It will be ob served that the upper ends of the arms 8 and 9 are extended to form enlarged flat hand gripping surfaces 24 to enable the operator to more readily grasp the device when inserting the rope and releasing the same. It will be observed that the length of the clamping arms 6 and 7 as indicated on the line 25, is such that there is plenty of surface or space between the outer edges 26 of these arms and the angular extending portions 10 and 11, whereby the entire width of the ends 4 and 5 of the rope are securely clamped as reference to Fig. 1 will clearly show or, in other words, the distance that these clamping plates 6 and '7 extend outward is substantially equal to the width of the rope 3.

What I claim is:

1. A device of the class described, comprising in combination, clamping members pivotally connected together, each member beingformed with a clamping surface for engaging the rope that is designed to be drawn around the outer surface of a pipe, a pouring spout connected to a member for directing the flow of molten material into the space between the meeting ends of the rope, and means for normally forcing the clamping plates toward each other.

2. In a device of the class described, the combination, of substantially parallel members, means for pivoting the .members to gether, a stop device for limiting the inward movement of the lower ends of said members toward each other, said members having clamping surfaces for holding the ends of a rope together, one member having a spout formed at the lower end thereof to direct the flow of the molten material.

3. Ina device of the class described, the combination with a pair of clamping members, means for pivoting the members together, a stop device for limiting the movement of the members toward each other, said members having clamping surfaces to receive a rope, one member having a pouring spout to direct the flow of molten material.

4. A device of the class described, comprising clamping members, said members being pivotally connected together, the lower ends of which are formed with plates for receiving a flexible packing or the like which is designed to be placed around the spigot end of a pipe section and close to the bell end of an adjacent pipe section for confining the flow of molten material, a pouringspout integral with one of the clamping plates, and locatedso as to direct the flow of the material through the rope and into the annular chamber surrounding the spigot end ofv a pipe, said pouring-spout being formed so as to conform to the upper surface of the spigot end of a pipe, and means for moving the clamping plates toward the rope so as to engage the opposite outer surfaces of the rope.

5. A device of the class described, comprising a pair of plates each having an arm for pivotally securing the same together, a stop device for limiting the movement of the plates toward each other, a spring attached to the plates for forcing the plates toward each other, one of the plates having an inclined spout connected thereto and the outer side of the spout being substantially triangular in form, its lower edge being designed to rest upon the spigot end of the pipe.
